إن التطور الهائل في جميع المجالات و التبادل التجاري بمختلف أنواعه و بشكل خاص البحري منه، نتيجة للتعاظم المستمر في حجم الحمولات المرافقة له، تبرز أهمية المرافئ بوصفها أهم المنشآت لرفد الاقتصاد الوطني و إنعاشه، لذلك كان لا بد من إعطائها أهمية كبيرة بالعمل على تطويرها و تحسين مواصفاتها الفنية (الأرصفة)، فالأرصفة منشآت معدة و مصممة لرسو السفن فيها، و تنوع الأرصفة المنفذة يتعلق بالمعطيات الجيوديزية و الجيوتكنيكية، و بطبيعة المواد المستخدمة ، بالإضافة لطبيعة السفن التي تؤم هذه المرافئ و حجمها. و تصمم جدران الأرصفة لتكون مستقرة و ثابتة، و لتحقق شروط الأمان المطلوبة لتأدية وظيفتها الخدمية دون إهمال للعامل الاقتصادي في أثناء عملية التصميم. في هذا البحث درست أنواع مختلفة من الأرصفة منفذة في دول مختلفة، و تمت الدراسة الإنشائية لأحد هذه النماذج (دراسة نموذج رصيف من القشريات ذات الأقطار الكبيرة) وفق الشروط و المعايير الخاصة بالجمهورية العربية السورية ممثلة بالمعطيات الجيوديزية و الجيوتكنيكية المحلية، و الحمولات الدائمة و المؤقتة المؤثرة، و استقرار النموذج المدروس و ثباته وفق الشروط المحلية، و أجريت المقارنة اللازمة لنتائج الدراسة الإنشائية للنموذج المدروس مع بقية النماذج المدروسة بالطريقة نفسها بغية تحديد أهمية هذا النموذج.
As the huge development in all life fields especially the commercial exchange with its variable types, more specifically the maritime, due to the continuous increase in the size of the accompanying big cargos. Ports significance emerges as the most important establishments to support the national economy. So, it has to be highlighted by working to develop and improve its standard specifications, particularly quays that are used for anchoring ships. The variety of quays link by geodesic-geotechnical features, material quality used and available for constructing, quality and size of ships that are anchored at these ports. The quay walls are designed to be stable and fixed to actualize the enquired safety conditions so it can offer its service employment without neglecting the economic factor during design operation. In this research, we will study variable types of quays constructed in variables countries of the world, the structural study had been done for one of these types according to the Syrian Arab Republic conditions with its local geodesicgeotechnical features, permanent and temporary effected loads, also stability and fixity of the studying type (maritime scurfy quay type with big diameters) according to local conditions and codes, proceeding the necessary comparative for structural study results of considered type for determining the importance of this type.

Existing supervised models for text clustering find it difficult to directly optimize for clustering results. This is because clustering is a discrete process and it is difficult to estimate meaningful gradient of any discrete function that can drive
gradient based optimization algorithms. So, existing supervised clustering algorithms indirectly optimize for some continuous function that approximates the clustering process. We propose a scalable training strategy that directly optimizes for a discrete clustering metric. We train a BERT-based embedding model using our method and evaluate it on two publicly available datasets. We show that our method outperforms another BERT-based embedding model employing Triplet loss and other unsupervised baselines. This suggests that optimizing directly for the clustering outcome indeed yields better representations suitable for clustering.
As a result of the industrial progress absolved by the world in all
fields, new materials have been produced that have excellent
engineering properties at low economical cost. Therefore, we have
done this research by greening a composite material with a metal
base (aluminum 6061) reinforced with stainless steel wire A304.
The aim of this paper is to study spin waves in ferromagnetic with spin (S=1/2) in complex coordinates system, the paper is divided into three sections:
The First section is about finding a transportation system that enables us to study a microsco
pic phenomenon ,its the spin waves in a classical way. The first step in this transportation system lies in finding the suitable wave function in the chosen coordinates, then the Hamiltonian and the Lagrangian then after that the dynamic equations in the general form, and testing the credibility of the system by making sure that it follow the rules of the study.
The Second section is about the use of that system, which is called the Simi classic way of studying the spin waves, and finding the dispersing equations and energetic levels then discussing the resultes from different ways and effects.
The Third section includes 1- Finding the ground state (basic) and the importance of finding the energy of the ground state lies in its direct effect on the system's energy.2- Finding the movement equations connected with time and place (the time-place equations). Its importance lies in two points; the first one is that it enables us to find the variance in the coordinates of the spin according to time. The second point is to know the spread speed of spin waves according to the chosen axle and the connection of the variation of domains (the magnetic sectors) with the spreading of spin waves and its speed
In recent years, time-critical processing or real-time processing and analytics of bid data have received a significant amount of attentions. There are many areas/domains where real-time processing of data and making timely decision can save thousand
s of human lives, minimizing the risks of human lives and resources, enhance the quality of human lives, enhance the chance of profitability, efficient resources management etc. This paper has presented such type of real-time big data analytic applications and a classification of those applications. In addition, it presents the time requirements of each type of these applications along with its significant benefits. Also, a general overview of big data to describe a background knowledge on this scope.
